HORSESHOE.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed November 24,1905. .Serial No. 288,912.

To all whmn it may concern:

Be it known that I, SILAS V. CLARK, a citizen of the United States ofAmerica, residing at 1426 Sandusky street, Allegheny, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Horseshoes, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inhorseshoes; and the invention has for its object the provision of anovel attachment which can be easily and quickly secured to a shoe toprevent an ani mal wearing the shoe from slipping upon ice or the likesmooth surfaces.

My invention aims to provide an attachment which will be extremelysimple in construction, strong and durable, and free from all danger ofbeing injured by constant use.

Briefly described, my improved attachment consists of a plate, whichconforms substantially to the shape of a shoe to which it is attached.The plate is provided with depending calks which are adapted to engagein a smooth surface and prevent an animal wearing the attachment fromslipping or falling upon said surface.

have devised novel means for securing my improved attachment to the shoeof an animal, whereby the same can be easily and quickly detached incase it is desired not to use the attachment.

The construction entering into my attachment will be hereinafter morefully described and then specifically pointed out in the claims, and,referring to the drawings accompanying this application, like numeralsof reference designate corresponding parts throughout the several views,in which- Figure 1 is a side elevation of my improved attachment, asapplied to a shoe. Fig. 2 is a top plan of the same. Fig. 3 is a bottomplan. Fig. 4 is an enlarged detail cross-sectional view of theattachment as applied to a shoe. Fig. 5 is a longitudinal sectional viewof the attachment applied to a shoe. Fig. 6 is a perspective view of theattachment-fastener which I employ for securing it to a shoe.

To put my invention into practice, I preferably construct my improvedattachment for horseshoes of steel or a material similar to the ordinarytype of shoes at present used. The shoe 1 which I use in connection withmy improved attachment has its heel-calks I The toe of the shoe isprovided to the shoe, conforms substantially to the shape of the shoe,said attachment or plate being provided with a depending toe-calk 9 andheel-calks 1O 10. The rear face of the toe of the plate or attachement 8is beveled, as at 11, to engage the beveled edge 7 of the transverse lug6. The outer edges of the plate or attachlnent adjacent to the heelsthereof are cut away, as at 12 12, to permit of the lugs 4 of the shoeengaging the plate or attachment 8. The inner edges of the plate orattach ment 8 adjacent to the heel-calks are recessed, as at 14 14, andin order to secure the plate or attachment to the shoe I employfasteners 19.

Each fastener consists of a pin 20, having an angularly-disposed stem 21and a flat proj ection 22, the projection being in alinement with thepin 20. A fastener is placed in engagement with the heels of the plateor attachment 8 and the shoe 1 by inserting the pins 20 in the piercedlugs 5 5 of the shoe. This, however, is accomplished before placing theattachment or plate 8 in engagement with the shoe, and when saidattachment is placed in position the stems 21 of the fasten ers 19 areadapted to extend upwardly through the recesses 14 14 of the attachment,while the flat projections 22 lie between the attachment and the shoeproper. This position of the fastener is clearly illustrated in Fig. 4of the drawings, and the stems 21 are adapted to be bent downwardly inengagement with the attachment, as indicated by the dotted lines 23 inFig. 4, whereby the shoe will firmly hold the attachment at its heels,while the transverse ridge 6 will prevent the toe of the attachment frombecoming separated from the toe of the shoe, owing to the beveledengaging faces 7 and 11. The toe and heel calks 9 and 10 10 of theattachment may be hardened and sharpened to engage smooth and induratesurfaces, and it will be impossible for an animal wearing shoesequippedwith my improved attachment to slip or fall upon such a surface.

Such changes in the construction of my inproved attachment as arepermissible by the appended claims may be resorted to without departingfrom the spirit and scope of the invention.

What I claim, and desire to secure by Letters Patent, is

1. The combination with a horseshoe having a depending transverse ridge,depending lugs carried by the heels of said shoe, of a plate adapted tofit upon said shoe, dependlng toe and heel calks carried by said plate,

I said plate adjacent to its heels being recessed to receive said lugs,the toe of said plate engaging said transverse ridge, fasteners lyingbetween said plate and said shoe, and engaging some of said lugs, andhaving stems extending through notches in said plate, said stems beingbent over into engagement with the underneath face of said plate,substantially as described.

2. The combination of a shoe having depending lugs, a depending ridge, aplate engaging said lugs and said ridge, fasteners inserted between saidplate and said shoe and engaging some of said lugs and having stemsextending through notches in the plate and engaging the underneath faceof said plate, substantially as described.

3. The combination with a horseshoe, of depending lugs carried by saidshoe, a plate adapted to fit upon said shoe and engaging said lugs,depending calks carried by said plate, fasteners inserted between saidplate and said shoe and engaging some of said lugs, each fastener havinga stem extending between the inner surface of the lug and the edge ofthe plate to a point below the lower edge of the lug, substantially asdescribed.

In testimony whereof I ailix my signature 40 in the presence of twowitnesses.
